MACHINERY FOR MAKING WIRE COUPLINGS.

SPECIFICATION forming part of Letters Patent No. 364,985, dated June 14,1887.

Application filed June 25, 1886. Serial No. 206,904.

To all whom it may concern.-

Be it known that I, \ViLLIaM E. BROOK, of. Plainfield, county of Union,in the State of New Jersey, have invented new and useful Improvements inMachinery for Making lVirc Couplings, of which the following is a full,clear, and exact description.

This invention relates to improvements in mechanism for bending andforming wire into couplings or links; and it consists in a clampingdevice for holding the wire, and certain combinations of lovers forshaping and con necting the ends of the wire to complete the couplings,as will be hereinafterdescribed and claimed.

Reference is tobe had to the accompanying drawings, forming part of thisspecification, in which Figures 1, 2, 3, 4, 5, 6, and 7 representt'rontelevations, respectively, of this mechanism in the various positions toform a coupling, commencing with Fig. l with a straight piece of wire,and progressing through the different stages to the completion of acoupling in Fig. 7. Fig. 8 represents an end elevation of the jaws of anordinary parallel vise, which may be employed as clamping mechanism tohold the wire while being formed into a coupling, and upon which themechanism to form the coupling is mounted. Fig. 9 represents a couplingcomplete, detached.

In the various illustrations from Figs. 1 to 7, inclusive, a view of acoupling is represented detached from the machine, in order to show moreclearly the various stages in forming the coupling and the various positions of the mechanism in the operations.

In illustrating my invention I have employed an ordinary parallel vise,A, upon which is mounted the mechanism to form a complete coupling froma straight piece or" wire, as shown in Figs. 1.to 7, and which may bedescribed as follows:

To the fixed or stationary jaw C, Fig. 8, of an ordinary parallel viseor other suitable clamping mechanism is firmly secured a horizontal bar,D, upon which bar are pivoted at F F two levers, E E, with projectinglower ends, which are provided, respectively, with friction-rollers G,by which the two ends of a straight piece of wire are to be bent upward(No model.)

in forming a couplin Projecting from the inner face of the fixed orstationary jaw O of the vise or clamp are four studs, II, around whichthe wire is to be bent to form a coupling, and which govern the shape ofthe coupling. A fifth stud, I, is placed centrally between the lowermoststuds H, which serves to support the straight piece of wire againstthese lowermost'studs; and to hold it in position to be bent by theaction of the frictionrollers G, as shown in Fig. 1.

In order that the straight piece of wire may be introduced properly andquickly into the machine, so that its two ends may be bent to connect,and thus complete the coupling, as shown in Fig. 7, an adjustable stop,J, is socured to the fixed bar D, against which the end of the wireis'placed, as also represented in Fig. 1.

' The wire B for a coupling having been introduced into the machinebetween the two lowermost studs H,and above the supportingstud I, andresting upon the friction-rollers G of the lovers E E, respectively, andfirmly clamped between the two jaws of the vise, the first movementtoward shaping a coupling is made by turning the lever E outward anddownward until its edge rests upon a stop,V,

which governs the length of its movement in that direction, as shown inFig. 2, thus bend ing a section of the wire upward and aroundthelowerleft-hand corner stud to form one end of the coupling, the leverE remaining in position, as shown.

The next operation is to reverse the movement of the lever E, by whichthe wire is bent horizontally and around the upper left-hand corner studH,which completes one end of the coupling, as represented in Fig. 3. Tobend the wire around this upper left-hand corner stud horizontally byreversing the movement of the lever E, a lever, K, is pivoted thereto,and is movable longitudinally through a slot, L, and is retained inposition to the side of the lever E by a projection, M, which takes intoa correspontjling notch formed in the edge of the lever E, asrepresented, so that when the movement of this lever E is reversed theedge of the lower end of the lever K will turn the end of the wiredownward, as shown in Fig. 3. One end of the coupling having been thusformed around the upperand lower left the wire is clamped between thetwo jaws to handstuds H, the next operation is'to form a hook or loop,R, on the end of the wire, as shown in Fig. 5.

The lower end of the lever K is provided with a recess to receivesufficient of the end of the wire from which to form thisloop, and bywithdrawing the projection M on the side of the lever K from the notchin the edge of the lever E the lower end of the lever K, guided bythepivot N in-.the slot L, may be drawn upward, so that the end of the wiremay pass into the recess in the end of the lever K the required distanceto form the loop, and then by retaining the lever E in position,andturning the lever K on its pivot N outward, the portion of the end ofthe wire therein will beformed into a hook or'loop, as shown .in Fig. 5,at which stage of the operation the lever K is withdrawn fromthe end oftheloop R, and, together with the lever E, is turned outward to theposition shown in Fig. 6, the edge of the lever'E resting upon the stopV, extending from the bar D.

The next operation is to form the opposite end of the coupling byturning the lever E outward and downward, the friction-rollerG, securedthereto,bending the wire upward and around the right-hand lower stud H,as also shown in Fig. 5. The movement of the lever E isthen reversed,and the end of a projectingstud, O, secured thereto, is broughtincontact with the wire at the proper point from the end, by which it isbent downward to complete the contour of the coupling, as represented inFig. 6.

The outline of the coupling having been properly formed by being bentaround the four studs H, as shown in. the several figures, anindependent and separate lever, P,having a recess in its bent end, isplaced over the straight end of'the wire, and by being turnedhorizontally a section of this straight end is bent around the loop R,which completes the coupling, as represented in dotted lines, Fig. 7 thecompleted coupling being also represented de tached from the machine inFig. 9.

In order that the wire may be clamped be tween the jaws of the-vise, orother suitable clamping mechanism, and firmly held in position therein,to be bent into a coupling, re-

cesses are formed in the movablejaw S, to rebe bent into a coupling. Inbendingthe wire one side of the coupling passes directly over thishook'T, so that when the movable jaw S is withdrawn the hook T draws thecompleted coupling off of the studs H,.leaving the machine in readinessto receive a straight piece of wire, from which to form the nextsucceeding coupling, the independent lever P having been removed fromthe end of the loop and the other pivoted lever, E, returned to theposition shown in Fig. 1.

Any other clamping device may be em-- ployed instead of the ordinaryparallel vise,

which I have shown as a convenient method v of illustrating myinvention.

Having thus fully described my invention, what I claim therein as new,and desire to secure by Letters Patent, is

1.. A machine for making wire couplings, constructed, arranged, andoperating substantially as herein described, consisting of a suitableclamp for holding the wire, a form around which the wire is to be bent,and the pivoted leversE E, to first bend the wire'upward' to formtheends ofacoupling, and having reverse movements by which the two ends ofthe wire are bent inward and toward each other, so as to form theremaining side and to be united to complete the coupling, as set forth.

2. The fixed or stationaryjaw C, from which project studs H, aroundwhich the coupling is to be formed, in combination with the movable jawS and system of levers, construetecharranged, andoperating'substantially as herein shownand described.

3. In combination with the clamping-jaws C S, for clamping and holdingthe wire, and studs H, around which the coupling is-formed, theextractinghook T,by which the completed coupling is withdrawn from thestuds H, substantially as herein'set forth and shown.

4. In combination with the clamping de vice for holding the wire and thelevers E E, for partially bending the wire to form a coupling, the leverK, mounted upon and pivoted to lever E, so as to slide longitudinallyinthe v side of said lever, substantially as and for the purpose hereinset forth.

5. In combination with the clamping mechanism for holding the wire andthe system of levers E, E,and K, for partially forming a wire coupling,the independent lever P, for completing the coupling by uniting itsends, substantially inthe manner herein set forth and described.
